So, we agree that politicians are playing their games to convince voters. It is part of the price we are paying for giving everyone a right to vote. There is certain wisdom in the community, but to a limit.
As to “live” constitution, I like the “contract” argument. I do not see your reply to that. If we have a doubt, we can always go to voters and to the States and let them clarify.
